Do 3rd party BACnet MSTP devices count as nodes on a BCX controller that is node limited?

Issue

Do 3rd party BACnet MSTP devices count as nodes on a BCX controller that is node limited?

Product Line

Andover Continuum

Environment

  • BCX controller
  • Third-party BACnet MSTP devices

Cause

Knowing the information will ensure there is not more node than the BCX controller specifies.

Resolution

Yes they do count as nodes. If you do go over the node count you will see operational problems with the BCX BACnet controller. The BCX controller will scan lock when it tries to perform a time sync to the MSTP network.

Modbus nodes communicating via xDriver are not part of the node count.
